Be it known thatl Er Mel: B. Esnxsnhw,

a citizenof the l'nited States, residing in the borough of'.\l:ii'iliattun, city, county, and State of New York, have invented acertain new and useful improved Coupling for (Jonverging Endsof(Ianopy-F' tandards for Showshowing the bosses in different angularposi I tion; Fig. l, a section on the line 4 4 of Fig. 2,

and Fig. 5 a section on the line 5 5 of Fig. 2. 1

When there are but four curved standards e springing from the base b, itis only necessary to adapt the coupling to bases of dill'erentrectangular shape that the pair of oppo site bosses c c and the pair ofopposite bosses (Z 11 should be adjustable with respect l to each other.,T he bosses c 0 may therefore be formed integrally with acentrally-apertured flanged plate C and the bosses d (l formed integralwith a corresponding centrally-apertured concentric llanged plate D. Byturning these plates with respect to each other the angular relation ofthe two pairs of radial bosses may be varied, as seen in Figs. 2'

and 3. The edges ol the abutting flanges of the plates (J 1) turn uponeach other and may be clumped together in des red position by means of abolt E, threaded to receive a clampuiut li. This provides for ad'ustingthebosses to different angles according to the width of the base 11,from the corners of which the standards spring. The belt E is preferablyformed with an enlarged head E and with a bore e, opening into a groovee which runs into a slot e n the lower end of the bolt. The bosses c care cut away at the bottom to accommodate the flange of plate D and thebosses d are cut away at the topto accommodate the flange of plate C.There are therefore openings f respectivel below and above the flanges,through either. of

I which an electric conductor entered in the bore 1; may be carried intoone of the hollow bosses and down through the corresponding standard,which may be hollow, or such an electrical conductor can be passedthrough v the groove 6 for the purpose ol afl'ording pended from theslot e.

Where it is desired to have additional l standards springing from theuse midway between the corners, either at 15 1e ends or at the -frontand back, an additional pair of bosses is required. They should bediametrically opposite the axis of the bolt E and ently of the otherpairs of bosses. complish this, the nut E is re laced by anut plate G,having diemetrical y opposite upturned parts formed as hollow bosses gg. This plate is also provided with an upturned illumination of anydevice that may be susshould be capable of adjustment independ To 210- 1i flange 9' "to form. a horizontal seat for the plate I). The nut-plateG may be set to bring its bosses in proper position to receive threeplates may then be securely clamped together by rotation of the bolt E.plat-es (J I) and bolt E are the same whether the head is adapted forfour or six standards, and where there are to be six it is onlynecessary to substitute the nut-plate G for the nut E. f

It is preferred, as shown, that the ends of formed by the bosses'insteadof havingthe standards fit over the bosses.

I claim as m invention 1. Acoupling or'convergent endsof cano y-'standards, con'iprising two plates adjusts is one upon another an eachhavin a, air of opposite bosses to hold-the stun er s, and means forclam ing the plates.

In testimony whereof I have hereunto sul)- scribed my name.
